Overview

Randomized trial investigates adsorption properties in modified erionite, suggesting potential for gas separation.

Key Points

  • This study aims to analyze the adsorption characteristics of nitric oxide and nitrous oxide on cation-exchanged erionite.
  • Investigated different temperatures during adsorption experiments.
  • Characterized samples using UV–Vis diffuse reflectance, EDX, FTIR, and Mössbauer spectroscopy.
  • Analyzed adsorption data using Freundlich, Langmuir, and BET models.
  • ZAPS-Fe and ZAPS-Cu exhibited optimal performance for NO/N2O separation at high temperatures and low concentrations.
  • Under low temperatures, N2O was adsorbed more rapidly than NO.
  • Adsorption capacity order at low pressures: ZAPS-Co > ZAPS-Fe > ZAPS-Cu, attributed to cation acidity.
